      It seems that Kenwood, Icom and Yaesu are moving to one common interface for packet radio centered around the same connector as the old PS2 computer mouse

        It seems that Kenwood, Icom and Yaesu are moving to one common
        interface for packet radio centered around the same connector as the
        old PS2 computer mouse connector. This makes it very handy since you
        can go to the computer store and buy a PS2 mouse extension cable for
        a few dollars and cut it in half for building an interface cable
        between your radio and your computer. I would assume that the V71
        radio is using the same interface as all the rest of the kenwood
        radios. A quick check of your radio's owner's manual to make sure
        the pins on the jack of your radio are the same as the pins described
        in the pinout diagrams in the photos area of this group would let you
        know for sure.

        I m using the Alinco DR-135 with my two embedded nodes. Someone in this group recommended that radio and it works great. This radio has a very large head sink

          I'm using the Alinco DR-135 with my two embedded nodes. Someone in
          this group recommended that radio and it works great. This radio has
          a very large head sink which with a couple of fans stays cool even
          with 100 percent duty cycle. It also has PL decode properly wired to
          the COS output to the embedded controller which is important for
          keeping noise out of the IRLP network.

          I have uploaded a wiring diagram to the photos area of this group for
          the Alinco DR-135 two meter rig. I believe that same diagram also
          applies to the Alinco DR-235 (220 MHz) and the DR-435 (440 MHz)


          The two meter radio is available from Ham Radio Outlet for $169 with
          free shipping inside the USA. Its also sales tax free if you don't
          live in a state where an HRO store is located.

            The only complaint I've seen from Alinco radio owners with these is
            the relatively slow CTCSS decoder. It takes a long time to figure out
            that a valid CTCSS signal went away.

            Here's a link to someone who fixed the problem by using an aftermarket
            Communications Specialists TS-64 encode/decode board for a decoder:

            I believe you are correct. The only other thing to watch out for is
            that these radios come now with the "optional" packet board installed
            and wired to the rear DB-9 connector. That board typically has to be
            removed/disconnected and the radio cable reconnected to the DB-9, I
            believe.

            And with 2m as busy as it is in most metropolitan areas, 2m is a
            really poor choice for a node that's going to get used a lot. 440 is
            better and 220 is a wide-open playground that needs activity anyway.
            Pay the few extra bucks for the higher bands.
